Samsung revealed that its Galaxy S III smartphone has hit 20 million sales in over three months. The phone launched in Europe in May, and the following month in the U.S.
According to reports, the device outsold even Apple's iPhone 4S to become the top selling smartphone in the U.S. in August. Apple Insider shares this data from the U.S. carriers, showing the Galaxy S III on top for Verizon, and Sprint and T-Mobile, and in second, behind the iPhone 4S for AT&T.
I wouldn't expect the Galaxy S II to be on top for long.
Rumor has it that the device will soon be getting the Android Jelly Bean update.
